PARIS (AP) — An Italian artist has decorated the Louvre museum's iconic glass pyramid for the first time with a message about capitalism.

Michelangelo Pistoletto, one of the world's leading conceptual artists, covered one panel of the pyramid with a huge three-looped infinity sign made of mirrors Wednesday. It's an artistic gesture aimed to show politicians and society the follies of excess that led to the financial crisis.

Pistoletto told The Associated Press that "politicians should looks at themselves in the mirror, and learn to take responsibility for this terrible mess and think of the infinite future ahead for humanity."

It's the first time an artist has worked on the outside of the pyramid, commissioned by former President Francois Mitterrand nearly 30 years ago.

Curator Marie-Laure Bernadac says "it's somewhat of an event."
